A mesoporous antimony-based nanocomposite for advanced sodium ion batteries

Ultrafine mesoporous Sb2O3@Sb nanocomposite was fabricated through a dealloying strategy, and shows superior Na storage properties (excellent specific capacity, ultrahigh rate capability and good cycling stability) as an anode for SIBs. Operando XRD and Raman techniques further reveal the Na storage mechanisms of the Sb2O3@Sb nanocomposite.276
